Oldbury Electrochemical

Commercial phosphorus trisulphide is largely PiS,. Phosphorus hepta-Rulphide is available inter alia from the Oldbury Electrochemical Company. 

Phosphorus heptasulfide was obtained from the Oldbury Electrochemical Company. It has been shown 2 that the phosphorus trisulfide used by earlier workers for such fusions was actually somewhat impure phosphorus heptasulfide. 

In America, phosgene was made from combination of carbon monoxide and dichlorine in graphite tubes. Daily production at the Federal site, known as the Edgewood Arsenal [819,954], was 40 tons at the beginning of America s late involvement in the war. The works were eventually extended to a capacity of 80 tons per day (although the plant was closed, shortly after the signing of the Armistice, and the extended production was never fully realised [1019]) [954], with a further 10 tons per day provided by the Oldbury Electrochemical Co. 

Castner, Hamilton Young — (Sep. 11, 1858, Brooklyn, New York, USA - Oct. 11,1899, Saranac Lake, New York, USA) Castner studied at the Brooklyn Polytechnic Institute and at the School of Mines of Columbia University. He started as an analytical chemist, however, later he devoted himself to the design and the improvement of industrial chemical processes. He worked on the production of charcoal, and it led him to investigate the Devilles aluminum process. He discovered an efficient way to produce sodium in 1886 which made also the production of aluminum much cheaper. He could make aluminum on a substantial industrial scale at the Oldbury plant of The Aluminium Company Limited founded in England. However, - Hall and - Heroult invented their electrochemical process which could manufacture aluminum at an even lower price, and the chemical process became obsolete. Castner also started to use electricity, which became available and cheap after the invention of the dynamo by - Siemens in 1866, and elaborated the - chlor-alkali electrolysis process by using a mercury cathode. Since Karl Kellner (1851-1905) also patented an almost identical procedure, the process became known as Castner-Kellner process. Cast-... 

There was no need for commercial quantities until near the turn of the century. At that time, it was made in Oldbury, England, by the Aluminum Co. and in Germany by Deutsch Gold-und Silber-Scheideanstatt, and a little later by the old Niagara Falls Electrochemical Co.
